March 14 Cla'ims. (01. 242-76) My invention relates to means forsupporting coils of such material as paper in the form of a ribbon orweb, it finding an especially usefulfield in the apparatus for makingbox-blanks which is the subject of an application for Letters Patentfiled in the UnitedStates- Patent Ofiice in my name on September 8, 1930and having the Serial No. 480,518. Of this pending application thepresent case is a division.

In apparatus for manufacturing box-blanksby the continuous-productionmethod, a web of pasteboard or other shell-material is advanced througha series of mechanisms for the performance upon it of variousblank-forming operations, and during this travel there may be adhesivelyattached to it a; web of lining-material or a web of cover-material orboth, these'being commonly of paper. The paper is supplied in a coil,and an objectof the present invention is to support and adjust the'coilin an effective manner, bringing about its correct delivery to theshell-web or to mechanisms which are to act upon'it. To gain this end, Imay mount upon a supporting frame spaced arms arranged to carry a coilof web-material and'associate' with these arms means arranged to moveboth simultaneously transversely 'of the web, and I further providemeans movable in engagementwith each arm and with the frame and arrangedto vary the position of each "arm independently, as either angularlyabout a pivotal axis or in the same direction as the simultaneousadjustment. By such an organization, the support may be caused todeliver webs of different widths in such a direction that they will runevenly or without lateral displacement to the point ofjoining theshell-web or through the apparatus. In the embodiment of the inventiondisclosed herein, I have employed a sleeve movable longitudinally of asupporting spindle and coil-carrying arms movable longitudinally of andangularly about the sleeve. Screws are preferably furnished foreffecting gradually the adjustment of the sleeve and the angularadjustment of the arms, and for fixing the arms in the chosen positions.It is desirable to maintain the edges of the convolutions at eachextremity of the mounted coil in substantially vertical alinement, toaid in the true delivery of the web from the coil, and for this purposeI may movably mount upon each coil-supporting arm a retaining member,together with means, as a screw, for moving said member. Variableconnections, conveniently consisting of a rod secured to the outer endsof the retaining members by set-screws, are shown for locking saidmembers in the relation thus established.

One of the several forms which my invention may assume is illustrated inthe accompanying drawing.

I have shown a fragment of a frame F, which may be that ofthe'blank-making apparatus to which is to be supplied a web of materialfrom a, coil W mounted in the following manner: Extendingtransversely'of the frame is a fixed spindle 124, about which may movelongitudinally a sleeve 126. Arranged for adjustment-upon the sleeve arespaced arms 128, 128 provided with horizontally alined depressions 130to receive a spindle 132, about which the coil W of web-material iswound. To hold the opposite edges of the successive convolutions of thecoil in the same vertical planes, each arm has an upwardly extendingretaining member 134 provided with horizontal guide-rods 136, 136passing through openings in' its arm. Turning in each arm is anadjusting-rod 140, prevented from moving longitudinally by collars'142,142 secured to the rod upon opposite sides of the arm. At 144, the rodis threaded into the adjacent arm. When either rod 140 is rotated by 'ahand-piece'146 upon it, the corresponding member 134 may be slid intothe desired retaining relation with the sides of the coil of material.Here, both members may be locked by a connecting-rod 148 passinghorizontally through openings in their upper extremities and secured byset-screws 150. l

It may be desirable, especially'in setting up the apparatus, to vary theangular relationof the arms 128 about the sleeve 126. This is useful inso locating the depressions130 that the coilspindle l32 will behorizontal, causingthe web at its opposite edges to leave the coil inthe same direction and thus without distortion. The adjustment is shownas effected by screws 152 threaded through depending portions 153 of thearms and contacting with an element of the frame. After adjustment, thearms may be fixed to the sleeves by set-screws 154. These setscrews alsopermit a variation in the positions of the arms horizontally of. thesleeve, to most advantageously locate said arms for coils which differin width. 7

The transverse position of the coil as a whole, and therefore thedirection in which the web FIDO as a whole runs, is shown as variable bya screw 156 shifts the arm and the sleeve 126, to which it is secured,in one direction or the other, and consequently adjusts across the pathof the material the entire coil-supporting structure. This structure ismade more rigid for this movement of the entire supporting assembly bythe rod 148 tying together the retaining members 134, 134.

Having described my invention, what'I claim as new and desire to secureby Letters Patent, of

the United States is:
